Method and Device for Training a Sensor Model for Change-Point Detection

A method trains a data-based sensor model for determining a change-point timing in at least one sensor signal of a cyclic technical process executed by a technical system. The method includes providing sensor signal time series of a sampled measured value and an associated change-point timing, and determining an evaluation signal time series by defining a regular evaluation time window over the sensor signal time series. The method further includes determining training datasets having the evaluation signal time series and the assigned change-point timing, and training the data-based sensor model with the training datasets. The change-point timing is provided as a classification vector. The classification vector encodes a time point within the evaluation time window by a position of an element of the classification vector and encodes a time point before and/or after the evaluation time window by a further position of a further element of the classification vector.
